Ultrasound-based tip location using transhepatic or subcostal views provides an accurate and intra-procedural assessment of the catheter inside the inferior vena cava, reducing the risk of primary malpositions of the tip. Malposition of a femorally inserted catheter into the ascending lumbar vein represents a rare but serious complication potentially associated with pain at infusion, vascular injury, retroperitoneal hemorrhage, and neurological complications. This paper reports a narrative review of this rare complication and the discussion of three clinical cases of femoral catheters inadvertently inserted into the ascending lumbar veins. This clinical experience suggests that ultrasound-based tip location should be implemented during femoral catheter insertion, since it is a rapid, easy, and safe method for ruling out this malposition.<\/jats:p>","DOI":"10.1177\/11297298261421383","type":"journal-article","created":{"date-parts":[[2026,2,24]],"date-time":"2026-02-24T04:53:52Z","timestamp":1771908832000},"page":"1496-1502","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Lumbar vein malposition of femorally inserted central venous catheters: Report of three cases and review of the literature"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3141-8974","authenticated-orcid":false,"given":"Stefano","family":"Benvenuti","sequence":"first","affiliation":[{"name":"Vascular Access Unit, ASST Spedali Civili di Brescia, Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edoardo","family":"Piervincenzi","sequence":"additional","affiliation":[{"name":"Department of Anesthesia and Intensive Care, Policlinico Universitario \u201cA.Gemelli,\u201d Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7574-1311","authenticated-orcid":false,"given":"Maria Giuseppina","family":"Annetta","sequence":"additional","affiliation":[{"name":"Department of Anesthesia and Intensive Care, Policlinico Universitario \u201cA.Gemelli,\u201d Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian","family":"Pintossi","sequence":"additional","affiliation":[{"name":"Vascular Access Unit, ASST Spedali Civili di Brescia, Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Chiarenza","sequence":"additional","affiliation":[{"name":"Vascular Access Unit, ASST Spedali Civili di Brescia, Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca","family":"Zanatta","sequence":"additional","affiliation":[{"name":"Vascular Access Unit, ASST Spedali Civili di Brescia, Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Facchetti","sequence":"additional","affiliation":[{"name":"Vascular Access Unit, ASST Spedali Civili di Brescia, Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno","family":"Marche","sequence":"additional","affiliation":[{"name":"Hematology Unit, Policlinico Universitario \u201cA.Gemelli,\u201d Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2225-7654","authenticated-orcid":false,"given":"Mauro","family":"Pittiruti","sequence":"additional","affiliation":[{"name":"Department of Surgery, Policlinico Universitario \u201cA.Gemelli,\u201d Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,2,23]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298231209253"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298211041442"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298211003745"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298241236816"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298251347084"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298241262821"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298211072407"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298211036002"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298221099838"},{"issue":"4","key":"e_1_3_2_11_2","first-page":"352","article-title":"Fatal neurologic complication of parenteral feeding through a central vein catheter","volume":"138","author":"Kelly MA","year":"1984","unstructured":"Kelly MA, Finer NN, Dunbar LG.
